public class SimpleMaximizingRuleSetOptimizer<E extends Comparable<E>>
extends RuleSetOptimizer<E>

Rule learning framework for mapping extractions onto an ontology. Annotations of rule instances are supplied, as well as corresponding extractions. For each annotation, a base rule is created by making a maximally constrained rule that results in the ontological relation given the extraction. Then the base rule is generalized using a search algorithm, by default beam search. A list of generalized rules are returned. There may be more than one value in the case of a tie.
